The Trinity Triathlon, developed in association with Crystal Palace Triathletes, is a legacy event from the 2012 Olympics and celebrates its 10th year in 2020.

Named British Triathlon Children’s Event of the Year (2016), and London Region Children’s Event of the Year on three occasions, the event is open to boys and girls aged 6 to 19.

Each year the Triathlon attracts over 500 competitors from all over the south of England.

From elite athletes, many of whom are in the GB squad, to first-time triathletes, our Trinity Triathlon is enjoyed by all.  With excellent pre-race information, and support and marshaling available on race day, all triathletes can enjoy a fantastic day!


Our next triathlon is on Sunday 28th June 2020
